The idea of testers and developers working together had floated for a while, but its implementation has begun to take place recently. The agile methodology has been the pioneer in creating collaboration between testers and developers.
When testers and developers join hands, there is a mutual transfer of knowledge, that benefits each party, as well as the business and all stakeholders.
Agile processes are iterative. For each iteration, developers and testers write and test more code, until the product is ready for release. Work is divided into manageable chunks and testing is not put off till the end of the development phase. This extensive collaboration ensures a high-quality final product.
Testing benefits development the most when it begins in the early stage of product development. Testers clarify requirements of features to businesses that give developers a better understanding of the code’s purpose. Testers write test cases from the feedback obtained from users. They confirm when the aimed functionality has been achieved.
Using software testing tools, tests are automated by a programmer or tester, depending on the type of tool being used. Testers generally shoulder this responsibility. Automation testing tools will increase test coverage and maintenance. Both testers and developers working on user stories make decisions about where automation testing can be used to trigger acceptance.
Testers take a risk analysis that gives direction on what parts require most testing. Risks with the code are estimated not simply from the perspective of functionality but also security, performance and usability standpoints. This helps in establishing priority for tests. For developers, awareness of test cases and their associated priority from testers becomes a source of motivation for constructing better code. The developing team puts more effort into improving the risk pro code to ensure it passes the test. Testers can introduce more tests later but the initial advice from testers paves the way for a less defective code from the developers.
Testers advice developers throughout the software development life cycle and not simply at the time of adding code into the repository, resulting in earlier identification of defects. This knowledge sharing improves learning in the group.
When testers know which areas developers have already tested, they can direct their attention to the areas less tested. Without this communication between testers and developers, both might end up wasting time in performing repetitive tests, and ignore areas without coverage. Thus, learning is two-way between developers and testers; each side has something to offer to the other.
All developers perform unit testing, validating every component of the software. Testers can understand from the developer’s testing about where the code gets most complicated. Testers get a grasp over the part of the code the developer finds most difficult. Testers can then guide developers on the specific issues they are having trouble with.
From the waterfall model, agile models enjoy the benefits of integrating code construction and testing. Agile processes give faster and accurate codes that traditional models do not, as both testers and developers have a team-oriented approach.
